Hi,

I'm not sure I understand what you are asking for. Did you implement a driver for the PDM sensor? There is no PDM example in the SDK, but the documentation describes how to use the driver in the PDM chapter.

PDM microphones are also used in our Smart Remote 3 for nRF52 reference design, see Digital microphones. Different component than you are using, but you may find something useful in the firmware package.

Best regards,
Jørgen

driver for the PDM are provided in the  nRF_Drivers. now how should i proceed for next

Are you using an old SDK version?

You need to include the driver in your project, and add functions to initialize and use the driver API, as described in the link I posted above.
